I feel like when I'm talking to Missy, she knows what I'm saying. Not all the time, but for example, when I say "come here" she comes. When I say "stop it" she stops what she's doing (for about 30 seconds, but still!) when I say "I'll be back in a minute" she screams less than she normally would when I leave the room. She doesn't speak at all, but she really seems to understand a lot of what I say to her. Am I going crazy, or is it possible that she actually does understand English?
